For the most part these days you better have some real good tires. The kind you can take on gravel roads, You know the main lines through the forest! As what you are going to find mostly is a Locked Gate almost every ware else.
I have been traveling the roads in the coast range since the 1970s and there for a wile actually I actually traveled the new cuts
['roads' right behind the cat that cut them, just days before]. These cuts were primarily, very roughly gouged out of the cut sand stone, rock, mud and slime on the surface with stumps and root piles pushed over the edges and most never went through and never even had a safe place to even turn around, without sliding off into the canyon. Or at least the fear of it hasn't yet been forgotten.
I finished my Jeep a few years back and it was a woods ready rig based on my last thirty plus years of travel in the hills. I have never been so disappointed in my life traveling around the coast range. No matter who has title to the property.
Even The Roads that the tax payers of Oregon paid to build and were guaranteed the right of use, are now gated walking trails only.
You will never miss what you never had, At least I have the memories.
